Why does the temperature rise as heat is being added when only one phase exists?

I think that the temperature rises when heat is being added because all of the energy has nothing else to focus on so it changes the temperature. Also, adding heat would make the temperature rise.

What determines the phase in which water exists by?
At this linksee the phase diagram of water.
What happens when heat is added to a system?
When heat is added to a system, the temperature increases, unless there is a phase change taking place. In that case, temperature remains the same, and the only observable difference is the phase change.
What happens to a substances temperature during a phase change?
stays the same
Rain exists in what phase?
. Liquid
As heat is added to a substance undergoing a phase change. why does the temperature remain?
Basically what it comes down to is the substance that is left behind during the phase change (say the liquid when it is changing to a vapor) has a lower internal energy than it had before the phase change started. To maintain the substance at its original temperature, an equivalent amount of energy must be added to make up for the loss of internal energy due to the phase change. (Conservation of Energy)The energy added in this case is heat, which in turn causes more molecules of the substance to change phases and lowers the internal energy & the process repeats. This is why the temperature remains constant as you add heat to a substance during a phase change. Once the phase change is completed the added heat will eventually cause the temperature to rise in the new phase of the substance. Hope this explanation helps. It's kind of hard to explain without a basic knowledge of thermodynamics.

Overcome intermolecular forces
What does a phase diagram provide?
"A phase diagram is a graph of pressure versus temperature that shows in which phase a substance exists under different condition of temperature and pressure" -Glencoe Chemistry Book

What happens to temperature as energy is added to a substance that is changing state?
The temperature remain constant during the phase changing.
How do you know that particles in a gas have more energy than particles of same substance as a liquid or a solid?
We know that for any given substance, and at a given pressure, the gas phase exists at a higher temperature than the liquid phase, which exists at a higher temperature than the solid phase. And temperature measures heat energy per molecule or atom, hence, gas particles have more energy than particles of the same substance in their liquid or solid phase.
Sometimes heat energy is added but the temperature stays the same when is this?
During a phase change.
Why doesn't the temperature change fast during a phase change?
Basically because there is energy needed for the temperature to rise or become lower, but energy is also needed to change the phase, so instead of the energy being used to change the temperature, it is being used to change the phase, therefore temperature does not change.
What happens to temperature when energy is added as heat?
Either the temperature will increase, or it will remain the same. In the latter case, there is a phase change, as when ice melts.
